To this we reply, that the word 'ether' can here denote the highest Brahman only, because it is designated as a different thing, &c. For the clause, 'That within which these two are contained is Brahman,' designates the ether as something different from names and forms. But, excepting Brahman, there is nothing whatever different from name and form, since the entire world of effects is evolved exclusively by names and forms. Moreover, the complete revealing of names and forms cannot be accomplished by anything else but Brahman, according to the text which declares Brahman's creative agency, 'Let me enter (into those beings) with this living Self (jiva atman), and evolve names and forms' (Ch. Up. VI, 3, 2). But--it may be said--from this very passage it is apparent that the living Self also (i.e. the individual soul) possesses revealing power with regard to names and forms.--True, we reply, but what the passage really wishes to intimate, is the non-difference (of the individual soul from the highest Self). And the very statement concerning the revealing of names and forms implies the statement of signs indicatory of Brahman, viz. creative power and the like.--Moreover, the terms 'the Brahman, the Immortal, the Self' (VIII, 14) indicate that Brahman is spoken of. 42. And (on account of the designation) (of the highest Self) as different (from the individual soul) in the states of deep sleep and departing. In the sixth prapa/th/aka of the B/ri/hadara/n/yaka there is given, in reply to the question, 'Who is that Self?' a lengthy exposition of the nature of the Self, 'He who is within the heart, among the pra/n/as, the person of light, consisting of knowledge' (B/ri/. Up. IV, 3, 7). Here the doubt arises, whether the passage merely aims at making an additional statement about the nature of the transmigrating soul (known already from other sources), or at establishing the nature of the non-transmigrating Self. The purvapakshin maintains that the passage is concerned with the nature of the transmigrating soul, on account of the introductory and concluding statements. For the introductory statement, 'He among the pra/n/as who consists of knowledge,' contains marks indicatory of the embodied soul, and so likewise the concluding passage, 'And that great unborn Self is he who consists of cognition,' &c. (IV, 4, 22). We must therefore adhere to the same subject-matter in the intermediate passages also, and look on them as setting forth the same embodied Self, represented in its different states, viz. the waking state, and so on.
